  • Information theoretic approach to quantization and classification for signal processing, communications, and machine learning applications

    Creator:
    Thuan Nguyen D.
    Abstract:
    There are five main contributions of this dissertation. The first contribution is new closed-form expressions for channel capacity of a new class of channel matrices. The second contribution is the discovery of the structure for optimal binary quantizer and the associated methods for finding an optimal quantizer that maximizes mutual...

  • Scaled modeling and simulation of ocean wave linear generator buoy systems

    Creator:
    Gore, Ganesh P.
    Abstract:
    Accurate scaled modeling and simulation are critical to advancing ocean wave linear generator buoys. A 100th scaled model of ocean wave generator buoy systems is analyzed by solving the Navier-Stokes equations. These equations are numerically solved using Computational Fluid Dynamics (CFD) by implementing the front capturing method. In this thesis,...

  • Prototyping a triple-layer phoswich detection system

    Creator:
    Duncan, Christopher L.
    Abstract:
    Multi-layer optically coupled scintillation based radiation detectors, known as phoswich detectors, have rapidly evolved in recent years. During the same time, digital signal processing has improved radiation discrimination accuracy and enhanced reliability, while reducing complexity and size of traditional analog signal processing methods. A new generation of high-speed radiation detectors...

  • Immune radio architecture for platform interference

    Creator:
    Alban, Eduardo
    Abstract:
    The decrease of switching times accompanied by the corresponding increase of clock speeds and data rates, contributes to improve the overall system computational performance. At the same time, they also affect wireless communications due to an increment in the emissions of electromagnetic radiation on the radio bands. In this dissertation...

  • Development of a CZT-Silicon Detection System in Support of the Comprehensive Nuclear-Test-Ban Treaty

    Creator:
    Alhawsawi, Abdulsalam M.
    Abstract:
    The Comprehensive Nuclear-Test-Ban Treaty (CTBT) bans all nuclear explosion tests for military or civilian purposes. The International Monitoring System (IMS) was established to verify compliance with the treaty. It consists of several monitoring stations that detect: seismic activities, hydrocoustic activities, infrasound waves, and radionuclide particles and noble gases. Radioxenon detection...

  • Generalized radix design techniques for low-power, low voltage pipelined and cyclic analog-digital converters

    Creator:
    Sharma, Vivek
    Abstract:
    This thesis proposes a novel technique for the design of pipelined and cyclic ADCs utilizing generalized radix gain stages. Several models have been proposed for the optimization of high performance pipelined ADCs by various researchers. This work builds upon them, using a simple but accurate model to estimate the optimal...

  • Variable sampling compensation of networked control systems with delays using neural networks

    Creator:
    Lopez-Echevarria, Daniel
    Abstract:
    In networked control systems (NCS) information or packets usually flow from a sensor or a set of sensors to a remotely located controller. Then the controller processes the received information and sends a series of control commands to the actuators through a communication network which could be either wireless or...

  • Real-time radioxenon measurement using a Compton-suppressed well-type phoswich detector for nuclear explosion monitoring

    Creator:
    Alemayehu, Bemnet
    Abstract:
    Radioxenon detection is a technique used to monitor nuclear explosion and verify the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Because of an ultra-low concentration of radioxenon at radioxenon monitoring stations, radioxenon detection systems must have high sensitivity. This sensitivity is measured in terms of detector's minimum detectable concentration (MDC). It is required...

  • Some contributions to asymmetric error control codes

    Creator:
    Elmougy, Samir
    Abstract:
    In some practical systems, most of the errors are of 1 → 0 type and 0 → 1 errors occur very rarely. In this thesis, first, the capacity of the asymmetric channel is derived. The capacity of the binary symmetric channel (BSC) and the Z-channel can be derived from this...

  • Layout dependent and bias independent scalable substrate model for RF MOSFETs

    Creator:
    Suravarapu, Ravikanth
    Abstract:
    The dependence of the substrate resistance, R[subscript sub], for MOS transistor RF modeling on transistor biasing and layout is studied from device simulations and measurements. Though R[subscript sub] is found to be bias dependent, the error incurred by assuming a constant value equal to the DC resistance is not significant....
